Notes. For all 28 bins, the energy, the number of signal and background counts (ON and OFF), the normalisation factor α, the statistical significance σ, the gamma-ray flux, and the energy range of the bin are given. The significance is calculated following Li & Ma (). For the final bin, as it has only marginally positive significance, we list both the actual flux point and the 2σ upper limit (which is drawn in Fig. 4). Note that the energy and flux values given here are corrected for the variation in optical efficiency, as discussed in the main text.
